Abstract

The cylinder has a piston (3) with a stopper (10) whose hollow body delimits a channel (14) and has a conical generator to create a passage with variable opening between the body and a housing (13). The passage communicating with the channel links the piston`s pressure chamber (8) with a fluid evacuation conduit (6). The stopper is applied against its seat to limit speed of displacement of the piston at piston`s end of course.
